Abstract

The invention relates to a method for producing water-soluble or water-swellable polymerizates with a very low residual monomer content using acrylic acid and/or acrylic acid derivatives which have been partially or completely neutralised with nitrogen compounds. The method is characterised in that the polymerizate is subsequently heated to temperatures of 120 to 240 °C. The polymerizates produced according to the inventive method are suitable for use as e.g. flocculants, dispersants and absorbers.
